A question.
When XL was healing XY, why did he ask, "Will you hate me?" Is it because of his demon blood that he gave to her?
Yes, he's worried that she will think he has turned her into a monster and she'll hate him for it.
He also asks if she'll hate him if TSJ dies. In the novel, there is no metric (like XY's celestial consciousness ghost becoming more solid) that shows that XY is "almost ready to wake up" at the end of the 37 years. It seems like maybe XL could have woken XY up sooner, but he wanted to keep her with him a little longer. And he finally decided to let her go only when TSJ was really about to die, because only XY could save him.
Edit: I’ve read comments from other fans suggesting that it might have been the opposite: XL made a special effort to wake XY up earlier (which is why the final healing session was so intense and painful) so she could go back and save TSJ in time. That explanation makes more sense to me.
